Nedbank Greenbacks Savvy bundle

I moved over my bank account to Nedbank. Part of the reasons I chose to move my bank account to Nedbank was because of the credit card offers and overdraft facilities. On the 25th of March, my salary was deposited into the new Nedbank account. Again on the 25th, I app**** for a credit card and over draft facility at the Grove branch. The system approved both my credit card and over draft, the dedicated banker sent me the pre-agreement contracts which I accepted and signed. Thereafter, I received a text message congratulating me about the approval of my Nedbank credit card. Since then, I’ve been awaiting the delivery of my credit card & the activation of my over draft facility- I made a follow up on 01.04.2022 with my dedicated banker, and to my shock- I was informed that both my credit card and over draft facility are declined. I asked the dedicated banker what are the reasons for the decline- she could not give any feedback on the reason for declining. I find this utterly frustrating and unfair, I have honoured my side of the deal- I switched my choice of bank to Nedbank and also ensured that my salary is also switched into Nedbank. I have been given offers for both the credit card and over draft facility by Nedbank, which I both accepted and signed. Why does Nedbank raise our expectations and give us false hopes? None of this makes any sense.
